Best Buy has started taking preorders for Windows Phone 8 devices from Nokia and HTC, starting on October 21. With a contract, the HTC 8X is available for $99.99; Nokia the Lumia 920 for $149.99 (both on AT&T).
The Lumia 920, unlocked, is $599.99. The HTC 8X, unlocked (and available in "California Blue" only, at this point) also is $599.99. There was no information on HTC 8X's availability or pricing on Verizon or T-Mobile (though HTC has said it is coming to both of those networks). The Lumia 920 is exclusive on AT&T for some unknown period of time. six months, according to a Lumia training video posted to YouTube by WPCentral.
Best Buy's Web site said that the devices were available for preorder online and in stores. That made me crazily -- and foolishly -- hope there might be demo units in the stores, even though the Windows Phone 8 launch, scheduled for October 29, is still a week away.
